Iron-reducing bacteria can convert the oxidized form of iron in clay minerals, called ferric iron, into the reduced form of iron, called ferrous iron, which can then reduce hexavalent chromium to trivalent chromium—the reduced, insoluble and less toxic form of the heavy metal that poses a lower risk of groundwater contamination. This study sheds light on the poorly understood process by which iron-reducing bacteria reduce ferric iron in clay minerals, resulting in ferrous iron that could then immobilize and detoxify chromium.http://phys.org/news322288636.html

The special properties of these elements that make them so useful in technologies including batteries and catalysts – for example, having multiple stable oxidations states under ambient conditions – also make them useful to living organisms.http://phys.org/news266484935.html

Most municipal or city engineers should be able to provide such a report upon request. Additional information specifically about hexavalent chromium levels may also be available.http://phys.org/news212240641.html
